The current through a coil as a function of time is represented by the equation I(t) = Ae-bt sin(wt), where A = 5.25 A, b = 1.75 x 10-2 s-1, and w = 375 rad/s. At t = 0.670 s, this changing current induces an emf in a second coil that is close by. If the mutual inductance between the two coils is 4.38 mH, determine the induced emf. (Assume we are using a consistent sign convention for both coils. Include the sign of the value in your answer.)
